Do high sulfur and nitrogen contents in the hydrogenation feedstock have an impact on the catalyst?
A high sulfur content in the hydrogenation feedstock can affect catalyst performance, causing it to become poisoned over time.
Organic nitrides in the raw materials can deactivate the active centers of the catalyst, thereby affecting product quality and shortening the catalyst’s cycle life. Of course, if the contents of olefins, sulfur, nitrogen, etc. in the raw materials are too high, it will increase the processing load on the catalyst and raise the severity of the operation.
The higher the content of impurities such as sulfur and nitrogen, the more easily the catalyst becomes deactivated. Catalyst deactivation is inevitable; what can be done is to maintain the catalyst’s activity and extend its service life.
